Amazon Under Threat From Cleaner Air

The Amazon rainforest, so crucial to the Earth’s climate system, is coming under threat from cleaner air say prominent UK and Brazilian climate scientists in the journal Nature.

The new study identifies a link between reducing sulphur dioxide emissions from burning coal and increasing sea surface temperatures in the tropical north Atlantic, resulting in a heightened risk of drought in the Amazon rainforest.

The Amazon rainforest contains about one tenth of the total carbon stored in land ecosystems and recycles a large fraction of the rainfall that falls upon it. So any major change to its vegetation, brought about by events like deforestation or drought, has an impact on the global climate system.
